I personally don't use Z80MU or even 22NICE all that much.  My
hard disk space is currently devoted to other tasks.  When I do
need to run a Z80-based application on an oddball setup, I go to
my CompuPro System 8/16 running Concurrent DOS 8/16.  I can run a
few well-behaved MS-DOS programs on it, like PKARC (PKZIP isn't
that well-behaved with CDOS).  Plus with SPUZ board, that thing
can run Z80-based applications like a bat out of hell with a Z80H
processor on it!  Also I have gobs of TPA space because "BDOS"
and "BIOS" (actually, the bulk thereof) are located outside of
the SPUZ's memory area (what IS in there is some code to prepare
to jump to the 86 XIOS code), so I can do some memory-intensive
stuff.

As for software emulation of a Z80, I have heard that the 68K
would be a better candidate for the job than, say, the 8088, or
even the 80286.
